To all whom it may concern:

Be it known that I, JACOB CLovE, a citizen of the United States, and a resident of Pendleton, Umatilla county, Oregon, have in: vented a new and useful Automatic Leveling Combined Harvester, of which the following is a specification, reference being had to the accompanying drawings as constituting a part thereof.

. My invention relates to traveling harvesters and has for its object to adapt'the Islalllne to be more effectively used on side To this end my invention has for its purpose to so arrange the machine and its wheeled support that the housing containing. the harvesting or thresher mechanism will substantially be maintained in verticalpo sition, whatever'the transverse incline of the ground over which the machine is traveling, so as to avoid any unduestrain on the-bearings of the working parts and facilitate the work of the latter.

I attain my object byjthe arrangement and combinations of parts as hereinafter described. I

Figure 1 of said drawings is a partial plan or top view of In combined harvester; Fig. 2 is a rear-end view thereof; Fig. 3 is a like rear-end elevation, showing my machineasoperating on a steep side hill; Figs. 4' and 5 are details of construction described in the body of the specification; and Fig. 6 iso per. spective detail of one of the Wheel frames;

The letters designate theparts described The running gear of .my machine com prises a body-frame, consisting of timbers a, a, a Near the lateral ends of' said bodyframe are pivoted, by suitable pivot bearings 0 wheel-frames b, b, inclu boxes (1, d, in which the axle ends of thew eelsc, c, are journaled. The wheel-frames I), b are sub: stantially alike in construction. Each of said wheel-frames comprises 'a horizontal rectan lar frame 5, on which are mounted vertica members b, b, and affixed cross-v wise on the latter is a top member b the arts" being braced and bolted as required. entrally mounted on the frame 12 are the axle-boxes d,d. I The-frame e of, the body or. housing closing the harvesting-mechanism, is pi'v oted, in front andrear, to the cross tinibers a, a, of the-vehicle body, by suitable pivot bearings of which only the" rear-bearing f can beseen in the drawings.

i In the front part ofthe vehicle body is (affixed an arched member or bar a, provided on one face with a series of cogs or teeth n.

. 'Said member at is conveniently constructed by taking two'bars n n curved and arranged concentrically, and afiixed intermediate of the upper segments thereof are a plurality ofradially arranged cog-like rods n, as shown in the detail, Fig. 4.

In the upper portion e of the frame of the housing e is j ournaled, inbearings, e a shaft bevel-gear p. Meshing with the latter are a pair of bevel pinions g, g, which are loosely mounted on-a horizontally j ournaled shaft g, and are rovided on their outer faces with in tegral oHOW-faced bevel-rimmed frictiongears s-, .s-. The latter are held' against-shift ing longitudinally on their shaft g by set grooves made on saidshaft. A detail of this arrangement is shown in Fig. 5. By observing the latter, it willbe seen that the shaft g is made with splines g at its ends, on which are slidably mounted the friction gears r, 1', having bevel rims adapted to engage with the hollow faces of the friction gears s, s, when moved into contact with the latter by theo eration of the/pivoted yoke, t. It will also e noted that the movement of'o'ne of the friction gears r, r into contact with its mnltaneously move the otherfgear (1' or 1") out of suchcontact. Theshaft g has an extension (1 on which is rigidly mounted a' sprocket-gear g, operatively connected by a sprocket-chain g (of which a part only is shown) with some convenient, sprocket-gear (not shown) on the projecting end of one of the driven shafts of the harvesting-mechanism. The yoke t is sup orted by an arm' t, rigidly mounted on a sliaft t journaledin suitable boxing sup orted on the frame-timrigidly mounted the pendent rod a of a pendulum-weight a.

In alinement with the wheel-axles, the housing e is'provided with 'a rectangular frame g, having exterior ortions h, respe-ce tively curved on their e ges to constitute segments of the sameciicle. Exterior of the curved portions hare afi'iiied slotted guide- 7', connected by hinged joint k, to arms I, rigidly afixed on the inner sides of the wheel- 0; fast on the lower end of said shaft is a pinion 0, and fast on the upper end thereof is a screws" 12, extending into circumferential bars i, in which are slid'a'hl y held CIOSS-llEitdS' corresponding friction gear (s or s) will si' I bers e, and on the ront end of the shaft 2 is frames 6, b. Thus the jointed connections between the wheel-frames and the housing frame of the machine cause the wheelframes to follow the movement of the former,

.or in other words, cause the wheel-frames to be moved up and down in correspondence with the movement of the housing frame, due to a transverse inclineof the ground over which the harvester is being operated.

Supposing now the shaft g to be continuously driven during the operation of my harvester, it will be apparent that so long as the harvester travels over substantially .level ground, there will be no eifect, but as soon as the harvester begins to travel over ground sloping to some degree, the pendulum will assume a relative position, thereby operating the yoke t, so as to bring one or the other of the friction gears r, 1" into operative contact with one of the corresponding friction gears s, 8; upon which the power of the shaft will be transmitted through the bevel-gears q,

l to the gear p, driving the latter during the period of time that the pendulum remains out of plumb; and thus driving the shaft 0, and thereby the pinion 0, which, meshing with the arched rack-bar 'n, will move the housing-frame relatively to the incline of the body-frame due to a transverse slo e of the ground, and thereby maintain the ousingframe in substantially vertical position notwithstanding said slope of the ground. It is further ap arent that after the housingframe has een moved relatively to the incline of the ground, and the latter again begins to return to a more horizontal plane, the pendulum will make a relative movement and in so doing operate the described devices, and thereby cause a corresponding movement of the housing-frame. And as a result of the described action, the body or housing of my machine inclosin the harvesting devices will maintain a suhstantially vertical position throughout the operation of my mac inc, and. the bearings of its operating parts relieved of any undue strain;

The front ends of the members a of -the housing frame extend over and are supported by the fifth wheel of the running gear, (not shown).

To restrain the lower end of the pendulum in case of a forward or rearward dip of my machine, while in action, I provide'a pair of transverse guide rods w between which the pendulum swings. To increase the arc of motion of the housing-frame the corners x, x thereofare beveled.
